Natural selection acts only on individual organisms and cannot affect the survivability of an entire species. a. true b. false

     The right answer to this question is option B. False.

Explanation:

      The main reason why this is not true is that natural selection is totally dependent on food chain and environment as a whole. This means that, there's a need of a whole population for a single organism to pass their adapted genes to another one. For example, if there's an environment with a certain kind of food for squirrels, and something happens to this environment that the food there is another type, if only one squirrel is born with the gene to eat this food, natural selection will kill not only this one at the end of its life, but the rest of the population that couldn't adapt to it.
